Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.
The RIPE NCC's transfer log records a transfer from TELE SAPIENS SRLS (RIPE NCC) to ADAL NETWORK SRL (RIPE NCC) on 2026-10-16 19:00 UTC. The registration changed hands; it is not a new allocation from the RIPE NCC.

Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2020-10-27 and allocated (dated 2020-10-28) on 2020-10-28. The tracker saw this range released from hold on 2020-10-27 (193.162.31.0/24), so it appears to have been issued again from the RIPE NCC's pool. Another change to this range was reported the day before or after (2020-10-27: Released 193.162.31.0/24), so the before-and-after statistics may include it.

The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2020-10-26 and available on 2020-10-27. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2020-04-30, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2020-10-28: Added 193.162.31.0/24), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2020-10-27. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 1993-09-01) on 2020-04-29 and reserved on 2020-04-30. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed IPv4 space for 180 days (six months), or longer while still routed, before reissuing it, so the estimated hold end is 2020-10-27. This does not confirm availability.
